Radeon HD 7850 vs Radeon RX 5600

Intro

Compare those specs to the Radeon RX 5600, which makes use of a 7 nm design. AMD has clocked the core frequency at 1375 MHz. The GDDR6 RAM is set to run at a speed of 1500 MHz on this model. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Radeon HD 7850		130 Watts
Radeon RX 5600		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

In theory, the Radeon RX 5600 is 92% faster than the Radeon HD 7850 in general, due to its greater data rate. (explain)

Radeon RX 5600		294912 MB/sec
Radeon HD 7850		153600 MB/sec
	Difference: 141312 (92%)

Texel Rate

The Radeon RX 5600 is quite a bit (about 220%) more effective at AF than the Radeon HD 7850. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 7850		55040 Mtexels/sec
	Difference: 120960 (220%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 5600 is superior to the Radeon HD 7850, by far. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7850		27520 Mpixels/sec
	Difference: 60480 (220%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
